| While using the test button on a GFCI is a quick and easy way to test its functionality, it may not always be enough to ensure its proper operation. The test button on a GFCI simply simulates a ground fault by creating an imbalance between the incoming and outgoing currents on the circuit. This test verifies that the GFCI can detect a ground fault and trip the circuit, but it does not confirm that the GFCI can handle a real ground fault.[br] |

| By using a Duspol or any other device to apply a load between hot and ground, you are simulating a real-world scenario where a ground fault occurs. This test verifies that the GFCI can detect and trip the circuit when a person comes into contact with the current and provides a path to the ground. This test also helps to verify that the GFCI is providing the required level of protection to prevent electrical shocks.[br] |

| In this guide, we will walk you through both methods and explain the steps you need to follow to test your GFCI. By the end of this guide, you will have a clear understanding of how to properly test your GFCI and ensure its reliable performance, helping you stay safe from electrical hazards.[br] |

| If your RCD covers your whole house, your whole house will lose power while you test it. Make sure that you don't have anything important, like a data transfer on your PC, running while you perform this test. |
